to the Sultan. The ayans agreed to assign their military units in the Sultan's army. The ayans promised to help to protect the Sultan's treasury. The ayans promised to obey the orders given by the Grand Vizier under the condition that the orders were not illegal. The ayans also agreed not to interfere in other ayans' sphere of influence. The Sublime Porte legitimised the ayans and their estates. Furthermore, the estates were declared inheritable. The ayans promised to support the Sultan against revolts. The Grand Vizier promised to consult with the ayans to solve taxation problems, while ayans promised not to oppress the poor. Aftermath According to some historians, the Charter of Alliance was a form of Turkish Magna Carta. Others, however; point out that the Charter, signed in the first half of the 19th century, can't be compared to the Magna Carta of the 13th century. In any case, the Charter was short-lived. According to the treaty, Alemdar's successors would also sign the treaty. But after Alemdar's death no Grand Vizier ratified the treaty, probably due to the sultan's only half-hearted support to it. The Sultan saw this treaty as a challenge to his prestige. In the following years however the energetic Sultan fought against the ayans and was able to subdue most of them.
